Non-linear function model of voice pitch dependency on physical and mental load.

Abstract

The present work describes that under increasing physical load the voice fundamental frequency (voice pitch) remains on a given level as long as the physical load is well tolerated by the subject, whereas heart rate and blood pressure continuously increase during increasing physical load. This voice pitch level was compared to voice pitch levels under mental load. Using a word recognition system, 11 well trained, young male subjects had to solve 2 moderate mental load tasks. Before, during and after each task, there were structured relaxation phases. The physical load protocol was a standard bicycle stress test. In each protocol phase the subjects had to count from 1 to 10 in order to provide a standardized speech sample. Heart rate and blood pressure were recorded in all phases. Voice frequency was at average 106 +/- 5.2 Hz in the relaxation phases ('rest level') and was increased under mental load (115.9 +/- 5.7 Hz, Pillais-P = 0.037). During physical stress testing, voice pitch remained unchanged ('tolerated load level') between 100 and 200 W (117.4 +/- 4.8 Hz) and increased shortly before physical exhaustion ('exhaustion level', 275-350 W, 142.9 +/- 5.6 Hz, Pillais-P = 0.007). In contrast, heart rate and blood pressure increased continuously with the physical load. Three voice pitch levels could be verified also individually for each subject. For the practical monitoring of emotional stress the individual anchor frequencies for these levels must be assessed. These data indicate that the relationship between both types of load and voice pitch is non-linear with multiple plateaus and transition functions between them.

  • Johannes et al. (2007) found that the interaction between physical load and speech proceeded in multiple plateaus rather than in a linear format.

  • In Johannes et al. (2007), there was no increase in F0 as long as physical load was well tolerated (workload between 100 and 200 W); F0 showed significant differences only at the pre-exhaustive stage and at the breakpoint of submaximal and maximal effort compared with rest-level and tolerated level.

    “Although significant increases in HR and systolic blood pressure (BP) were observed in relation with increasing physical workload, there was no increase in F0 as long as the physical load was well tolerated by the subjects (i.e., workload between 100 and 200 W). It was only at the pre-exhaustive stage and at the breakpoint of submaximal and maximal effort that F0 showed significant differences in”

  • In Johannes et al. (2007), time pressure and problem solving tasks evoked significant increases in F0 comparable with those found in the same study during physical activity within a tolerable level.

  • Physical load does not impact the voice as long as this load is well tolerated by the subjects.

    “However, physical load does not impact the voice as long as this load is well tolerated by the subjects (Mohler, 1982; Johannes et al., 2007).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
